Sex- and Age-Dependent Changes in the Adiponectin/Leptin Ratio in Experimental Diet-Induced Obesity in Mice.

ABSTRACT: Biological sex and aging impact obesity development and type 2 diabetes, changing the secretion of leptin and adiponectin. The balance between these factors has been propounded as a reliable biomarker of adipose tissue dysfunction. Our proposal was to study sexual differences and aging on the adiponectin/leptin (Adpn/Lep) ratio in order to acquire a broader view of the impact of consuming an high-fat diet (HFD) on energy metabolism according to sex and age. Male and female C57BL/6J mice were fed a normal chow diet or an HFD for 12 or 32 weeks (n = 7−10 per group) and evolution of body weight, food intake and metabolic profile were registered. The HFD triggered an increase in body weight (p < 0.001), body weight gain (p < 0.01) and adiposity index (p < 0.01) in both sexes at 32 weeks of age
